[c-nsp] SFP's (Third party) for ME3600

Have you tried the hidden global command... "service
unsupported-transceiver"

This worked for me when I couldn't get sfp's to work.  My notes below...

after typing that global command, just shut/no shut the port and it should
immediately start working.  you won't need to reboot me3600 nor will you
need to reinsert the sfp.  it will work.

insert sfp...  "show log" will show bad crc error and port in err-disabled
mode.
 
sh int status err
sh int g0/23

...will show port in err-disabled

sh inventory

...will not be listed at first.

...will be down down on "sh ip int br"

conf t
int g0/23
shut
no shut

sh inventory

...will now show like this...

Similar issues here.  The only 1000BaseT SFPs that we've gotten to work are
the Cisco branded ones.  Some of the other brands/manufacturers we've used
have given mixed results.  In one instance we had plugged in a 10/100/1000
SFP and tried connecting it to a Cisco 3750 FE port.  The FE port on the
3750 would come up but it would not come up on the 3600X side.  Swapping the
SFP with a Cisco branded one would resolve the issue most of the time.  The
3600X has proven to be one of the more finicky switches in terms of
accepting non Cisco branded SFPs.
